WATER; AND AIR FAN,

ppl a ipn d J l This invention relates, to, improved pro.-

pelling means for both land and] air vessels,

tan s. adj tabl co i -b l nc n m ns s p or d t r QQQn rat o change the action thereof.

My principal aim is to generally improve upon, structures of'thisgeneral class by pro- Vidillg one of comparative simplicity and durability, which is such as to render it exceptionally practical and advantageous.

Structural features will become apparent from the following description and draw- .ings.

In the accompanying drawings forming a part of this application, and in which like numerals are employed to designate like parts throughout the same a Figure l is a side elevation of the plane,

Fig. 2 is a side view of the plane mounted on one end of the oscillatory support,

Fig. 3 is a top plan view showing the oscillatory supporting bar with. movably mounted planes at the opposite ends thereof,

Fig. 4: is a side view of the structure shown in Fig. 3,

Fig. 5 is a view showing an end portion of a vessel equipped with a modified form of the invention.

In Fig. 1 it will be seen that the form of wi hi e P ane t plane there indicated comprises segmental blades attached to a central mounting piece 2. The plane is indicated generally by the reference character 1. Referring then to Fig. 2, it will be seen that this plane '1 is mounted between a pair of fixed abutments 4: which are rigidly secured to one end of the supporting bar 5. The blade or plane is pivotally between these abutments as is indicated at 3. The abutments may be of' any suitable form, being preferably of the curvature shown.

The bar 5 is adapted to be pivotally mounted as at 6 upon the vessel or other craft to which it is connected. It may be provided 1 4. semi m- 4 5 7- at itsopposite ends with, an. opening 7 for passage. of operating means (not shown).

Referr ng now to. Fig. 3,'it will be seen counter-balanced planes are. shown. The plane. at the left hand end of the bar 5 is the same as the one already described with thelezrception. that it is provided with screw members 8 having adjusting, nuts 9 mounted thereon. These nuts 9" constitute weights and by adjusting them longitudinally on the threads of" the, members 8, it is obviousthat the activity of the planecan'v be varied. The plane. at the opposite end, of the. bar 5 is substantially the same. except that it is made in spaced sections, and-each section is disposed on. an opposite sideIof; the bar 5.

Here, it will'beseen that the same counterbal ancing. means is provided, but that a pin 10 is added and, is extended between the threaded members 8 and is adapted'to cooperate with the aforesaid abutments for limiting the degree of swing of this particular plane.

The only addition in Fig. 4; is the member indicated at 7* which is employed for operating the rod 5.

Attention is now directed to Fig. 5, wherein a structure is shown which is such that it can be used for turning a vessel around in substantially its own length. In this form of the invention, in case of a storm, when it is'necessary to heave to, the plane can be turned to the proper angle with respect to'the keel to keep the ships bot to the wind. Furthermore the proper manipulation of this structure about to be described will aid in the efficient navigation of the boat. In this figure, the plane is generally designated by the reference character 1, the abutments by the character 4: and the pivotal connection by the character 3. In this in stance, these parts are mounted on a vertically movable shaft which is generally indicated at 11. The lower portion of this shaft is cylindrical in cross section and operates through a guide opening in the guide mem-.

ber 17. This guide member 17 is connected at one end to a part of the rudder 15 and at its opposite end to the body of the boat above the keel 18. There is an overhanging portion 14 at this end of the boat and the stern is designated by the reference character 19. It will be noted that the upper end of the shaft 11 is polygonal in cross section and operates through a block 13 which is fixed to the deck of the stern.

Vthile it is not plainly shown, it is to be stated that this block 13 is provided with a hole of cross section corresponding to the polygonal upper part of the shaft. Surrounding the cylindrical portion of the shaft at a point indicated in dotted lines, is a cou pling with which the operating member 5 has pin and slot connection. lVith this arangement, the member 5 is oscillated, the shaft 11 is reciproeated to operate the swing ing plane in the usual way. If it is desired to turn the plane around to the dotted line position indicated, a handle 12 is fitted on the square upper end of the shaft and when the cylindrical portion of the shaft is within the square opening of the block 13, it is obvious that the entire shaft can be turned around to accomplish this.

Various advantages and features of an invention of this kind will be clear to those skilled in the art to which the invention relates. Therefore a more lengthy description is thought unnecessary.

lVhile the preferred embodiments of the invention have been shown and described, it is to be understood that minor changes coming within the field of invention claimed may be resorted to if desired.

I claim- 1. Propelling means of the class described comprising a support adapted to be mounted for oscillation, spaced abutments carried by said support, a propelling plane pivotally mounted on the support for limited movement between said abutments, and counter balancing means carried by said plane.

2. Propelling means of the class described comprising a supportadapted to be mounted for oscillation, spaced abutments carried by said support, a propelling plane pivotally mounted on the support for limited movement between said abutments, counter balancing means carried by said plane, said counter balancing means being adjustable to vary its action.

3. Propelling means of the class described comprising a supporting member, spaced abutments carried by said member, a propelling plane pivotally mounted upon the member and adapted to swing in a limited are between said abutments, an arm carried by and extending from said plane, and counter balancing means adj ustably mounted upon said arm.
